Neuroscientist Warns About Three Hidden Risk Factors That May Increase Alzheimer’s Disease Risk

Alzheimer’s disease is often believed to be a condition that only affects older people. However, experts say that the factors which raise the risk of Alzheimer’s can begin much earlier in life. The habits we follow daily, the food we eat, how we sleep, and how we take care of our bodies can all affect our brain health over time. These small changes build up slowly and may show their effects many years later.

Robert Love, a neuroscientist who studies Alzheimer’s prevention, shared important information about this issue. In a video shared on social media, he discussed three major factors that can increase a person’s chances of developing Alzheimer’s disease. He explained that vitamin deficiencies, chronic inflammation, and poor sleep habits can slowly harm the brain and increase memory loss risk later in life.

Robert Love’s message is clear: brain health is not only about age. It is about everyday lifestyle.

He first spoke about vitamin D deficiency. Vitamin D is known as the “sunshine vitamin” because our body makes it when we are exposed to sunlight. Vitamin D supports the brain, bones, and immune system. But today, many people spend most of their time indoors at work, school, or home. This means they are not getting enough sunlight. Robert said, “Most of us don't get enough vitamin D because we spend most of our time inside.”

A lack of vitamin D can weaken the brain’s ability to protect itself. Robert suggests getting at least 20 minutes of sunlight every day when possible. If sunlight is limited due to weather or lifestyle, a vitamin D supplement may help, but only after talking to a doctor.

The second factor Robert pointed out is chronic inflammation. Inflammation is the body’s natural reaction to injury or infection. But when inflammation becomes long-term, it can quietly damage healthy cells, including brain cells. Chronic inflammation is linked to several health issues like diabetes, heart disease, and now, Alzheimer’s disease.

Inflammation can be caused by unhealthy food choices, especially eating too many processed foods, fried foods, sugary drinks, and chemical additives. Stress, lack of physical activity, and smoking can also increase inflammation in the body. Robert suggests choosing fresh fruits, vegetables, nuts, whole grains, and clean protein sources. Also, regular exercise, even light walking, can help reduce inflammation and support better brain function.

The third factor he discussed is poor sleep. Sleep is not just rest. It is the time when the brain repairs and clears waste materials. When a person does not sleep enough, harmful proteins can build up in the brain. These proteins are linked to memory problems and Alzheimer’s disease.

Robert explained that many people do not give enough attention to sleep. Some stay awake until late at night using phones, watching television, or working. Poor sleep over many years can harm the brain. Experts suggest that adults should try to sleep 7 to 8 hours every night. Keeping a regular sleep schedule, reducing screen time before bed, and creating a calm environment in the bedroom can improve sleep quality.

Alzheimer’s disease is one of the fastest-growing health concerns worldwide. While there is no full cure yet, research suggests that prevention may play a strong role in protecting the brain. The choices we make today can build a healthier future for our minds.

This information is especially important for young and middle-aged people. Many believe brain diseases only need attention later in life, but early awareness can make a large difference. Taking small steps now, like getting sunlight, eating fresh foods, managing stress, and sleeping well, may help reduce the risk of Alzheimer’s in older age.

Robert Love’s message encourages people to look at brain health as a lifelong practice. Our brain supports everything we do — thinking, learning, remembering, working, and connecting with others. Protecting it early ensures better quality of life later.
